Double Langmuir probe measurement of plasma parameters in a dc glow discharge
In this paper, plasma main characteristics such as electron mean temperature, electron number density, and oscillation frequency have been measured experimentally using the double Langmuir probe diagnostic system. In our experiment, the plasma was generated by applying the low pressure dc glow discharge in several common gases. The experimental results indicated the highest plasma density and o...
متن کاملDust particle charging in DC glow discharge plasma
Dust particles charging in a stratified positive column of a low-pressure DC glow discharge was investigated theoretically. The presented model consists of (i) previously developed 1D selfconsistent model for discharge parameters on the tube axis; (ii) ambipolar approximation for radial electric potential distribution and the assumption that the electron energy distribution function in radial d...
متن کاملObservations of a structure-forming instability in a dc-glow-discharge dusty plasma.
By adjusting the anode current and axial magnetic strength of a dc-glow-discharge dusty plasma, we have found plasma and dust conditions conducive to dusty plasma structurization, similar to the one discussed theoretically by Morfill and Tsytovich [Plasma Phys. Rep. 26, 682 (2000)]. The structurization instability leads to the formation of a pattern where the dust suspension transforms into alt...

متن کاملGeneration of Plasma Induced Flow Actuation by DC Glow-like Discharge in a Supersonic Flow
Plasma induced flow field modification is studied experimentally using non-equilibrium DC surface discharge in a Mach 3 supersonic flow. An array of small pin electrodes (φ = 3/32”) is used in streamwise plasma discharge configuration. The schlieren imaging shows that an oblique shock can be obtained with a volumetric glow discharge on the cathode with a relatively low current (as low as 50 mA)...
